. internal combustion c it known that L Lewis I). NnLsoN, a c. cen ofthe United States, residing at Union tdity. in the county of Branch andbltate of llliichigan, have invented certain new and-useful improvementsin Internal- Combustion Ei'igines, of which the following aspecification.

"lihis invention relates to improvements in engines.

The main objects of this invention are:

lihiret to provide in an internal combustion engine, an improyedstructure in which the exhaust and inlet manifolds are housed so thatthe inlet ma ui'fold is heated the housing constituting an air heaterfor the carloureter.

Second, to provide a structure having these advantages adapted to beattached to an engins, such as the "Ford," without changing the same andwithout the necessity for drilling or tapping for the securing of theadded parts.

Further objects, and objects relating to structural details. willdefinitely appear from the detailed description to follow.

ll accomplish the objects of my invention by the devices and meansdescribed in the following s 'uecitication. The invention is clearlydefined and pointed out in the claims.

A. structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification. in which:

lligure I is a detail side elevation of a structure embodying thefeatures of my invention, the engine being shown conventionally.

Fig. H is a detail plan view of the structure shown in Fig. I.

Fig. H1 is an inverted View of my iInproved manifold housing.

Fig. 1V is a detail vertical section through the mani Folds and thehousing on a line cor-- responding to line 4 l of Figs. I, H and HI.

ln the drawing. similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends ol. the section lines.

Referring to drawing, 1 represents the Specification of Letters Patent.

body of an engine such as that employed in a Ford automobile, th samebeing shown in conventional form. 2 indicates the en haust manifold andl the carburetor. The carhureter is provided with an air intake pipe 5and is connected to the arm (3 of the intake manifold The manifolds aresecured by the clamping yokes 7 and the bolts 8. the manifolds and yokesbeing partially shown by dotted lines in Fig. l the same being the usualyokes and bolts found on Ford automobile engines except that one of thebolts is removed and a lon er bolt substituted therefor, as shown in lig. 1V, which bolt is employed as a securing means for the housm Myimproved housing comprises a front section or member 9 having bosses l0and ill for the manifold securing yokes and bolts, the long bolt 8 beingarranged through the boss ll and provided with a clam ping nut 12 forthe housing. The front or main body section of the housing is providedwith integral end walls. The top section 13 ol the housing is adjustablysecured upon the front section 9, the top section being provided withprojecting arms 14 on its front end having slots 15 therein to receivethe bolts 1(l\\"l1crcby the top section may be adjusted to close the topof the housing above the manifolds or to provide an opening to regulatethe degree of heating as may be desirable in hot and cold Weather, Thebottom of the housing is closed by the rear section '17 which is disposed under and projects upwardly at the rear ofthe intake manifold 3.see Fig. IV, the same being removably secured to the front section bythe bolts 18 disposed through opposed cars on the rear section and onthe front section. see Figs; I and Ill.

The front and rear sections have complementary extensions 19 and 20respectively embracing the arm 6 of the intake manifold, andcomplementary sections 21 and 92 respectively providing an air intakepipe connection. A collar 23 is arranged on this air intake connectionto slip over the end of the air intake pipe. the collar being secured bymeans of the set screw 24;. The front section of the housing is providedw th an inlet openingEZS, preferably disposed near the an intake pipeconnection, it being desired the the air passing to the air intake pipeshould not be excessively heated. To further regulate the amount of heatpassing through the air intake pipe it is provided with a damper likealvc 26 which may be opened or partially opened to regulate thetemperature of the air passing to the carburetor.

With this arrangement of parts the housing may be quickly applied andthe parts are economical to manufacture and the structure is foundhighly eflicient in use.

I have not in the accompanying drawing attempted to maintain therelative proportions of the various parts, that of the engir carbureter,and manifolds, as the same vary in engines of different manufactures.

' Further, I have not attempted to illustrate various adaptations thatare possible and contemplated by me as I believe the dis closure madewill enable those skilled in the art to which my invention relates toeml'iody or adapt the same as may he desired.

Having thus described my invention, what I claim as new and desire tosecure by liet ters Patent, is:

1. The combination with an engine body, intake and exhaust n .uifoldsand scouring yokes and bolts theri ior, and a carburetor,

- of a housing comprising a front section disposed in front of saidmanifold and having' bosses for said yokes and bolts, one of the boltsbeing disposed through said front section and provided with a nut. saidfront section being}, provided with integral end walls, a top sectionadpistably mounted on said front section to coact with the engine bodyto close the top of the housing or when raised to admit air theretoabove the manifolds, and a rear section disposed below said manifoldsand detachably secured to said front section to close the housingbelowsaid manifolds,- said front and rear sections having complementaryextensions for said intake manifold.

2. The combination with an intake and exhaust manifolds and securingyokes and bolts therefor, and a carburetor, of a housing comprising afront section disposed in front of said manifolds and having bosses forsaid yokes and bolts, one of the bolts being disposed through said frontsection and provided with a nut, said front section being provided withintegral end Walls, and a top section adjustably mounted. on said frontsection to coact with the engine body to close the top of the housing orengine body,

, when raised to admit air thereto above the manifolds.

3.
